To all whom it may cof/wem:

Be it lmown that l, EDGAR l. HILL, a citizen of the United States,residing at @ak Park, county ci' Cook, State yof lllinois, have inventeda certain new and useful improvement in ironing Machines, and declarethe following to be a full, clear, and exact description of the same,such as will enable others skilled in the art to which it pertains to.make and use the same, reference being had to the accompanying drawings,which form a part of this specification.

i This invention relates to ironing machines and the object oi' theinvention is to provide an ironing machine consisting or" a feed rollerover which clothes are ined and brought into contact with a heatedironing shoe which is stationarily positioned in the frame of theironing machine. Another ob-v ject. of the invention is to provide ameans :tor moving the roller toward or from the heated-ironing shoe thesaid means also moving thedriving mechanism into or out of drivingengagement. fr further object or" the invention is to provide a drivefor an ironing machine which.is very simple and which may he connectedor disconnected by movement oi a lever, the said lever heing primarilyarranged for moving the roller of the ironing machine toward and 'fromthe ironing shoe. Another object o'the invention is to provide a worm:tor driving the ironing machine which, when the roller is moved towardthe ironing shoe is moved to driving engagement with worm gear, throughwhich the machine is driven and, when the roller is moved away from theironing shoe, the worin is moved ont oimesh with the worm gear. Theseobjects and the several novel Yfeatures of the invention are hereinaftermore iully described and claimed and the preferred form ci constructionby which these objects are attained is shown in the accompanyingdrawings in which l l is an end view of an ironing machine emhodying myinvention.

Fig. 2 is a similar view showing the mechanism in the driving position.

Fig. 8 is an enlarged section talren on line 3-8 of Fig. 2.

Fig. i is an enlarged section oi the yieldable connection hy which thefeed roller may be moved toward or 'from the ironing shoe.

The ironing machine comprises a frame l having supporting legs 2 andhaving a iiat table top 3 as shown in dotted lines in Figsl and 2. TheJrameworlr l is provided with a 'oraclret a on which is mounted anelectric motor 5 for driving the ironing machine. The motor 5 isprovided with a shaft 6 having a ange 'l' on the end thereof providedwith a series of pins 8 extending from the face thereof. rlhese pins 8engage in radial slots provided in the member 9 on the lend oi the shaftl0. The shaft l0 is rotatably mounted in hearings ll on a plate l2 and aworm i3 is secured to the shaft l0 between the hearings ll. rThis platel2 is provided with a pivot la which is rotatably mounted in the frame lso that when the plate 12 is swung down. on the pivot lll as shown in l"ig. l, the worm i3 is out of mesh with the worm gear l5 and when theplate l2 is swung up as shown in Fig. 2 the rworm 13 meshes with theworm gear l5. ln this position the mechanism is in the driving positionand a small gear 16 is provided on the shaft i7 of the gear l5 and thissmall gear lo meshes with a larger gear 18 which is secured to the outerend of the shaft 19. An arm shown inFigs. l and 2 is rotatably mountedon each end oi the shaft E17-and at the upper ends are provided withhearings for the shaft 19 in which the shaft i9 is rotatably mounted andthe shaft 19 is movable through a slot 2l provided in each end of theframe. iThe shaft 19 is provided with hearing 2O on each end thereof asshown in Figs. l 2 in which the shaft is rotatahly mounted the purposeoi which is hereinalter more fully described. Between the ends of theame is a roller or drain 22 'which is secured to the shaft 19 and whichis preferably covered with several layers oi cloth or a cloth '.oad asmay he desired. This roller 22 is the `feed roller for the maehine andthe clothes to be ironed are placed on the table top 3- and are `ed ontothe roller therefrom. in ironing shoe 23 is secured to each end oi' ltheframe and extends from one end to the other and the :tace 2i of the ironshoe is formed on a radius equal to the radius oi' the drum or roller22, the said shoe heing outwardly 25 so that the clothes will not catchthereon when heing carried around by the roller. rihis ironing shoe isprovided with a sheet metal casing 26 which encloses a gas hurne 27 'forheating the shoe, the said gas burner being adapted for connection witha gas feed line as will be readily' understood. The bearing 20 isprovided with a boss 28 on one side thereof and a shaft 2 9 is securedtherein by a pin` 30 as shown in Fig. 4. This shaft 29 is provided witha slot 31 therethrough and an aperture is provided in the end for thestud 32 which is threaded in to a member 33. This stud 32 is providedwith a pin 34 adapted to ride in the slot 31 and prevent the members 29and 32 from pulling apart, as willbe readily understood. The member 33is `provided A with a recess 35 in which the end of the shaft 29 maymove and the said member is also threaded on the outside at 36 toreceive a nut 37. A coiled spring is interposed between the nut'37 andthe shoulder 38 of the boss 28 and by adjusting the nut 37 on thethreads 36 the tension of the spring 39 may be increased or decreased asdesired. This spring normally holds the members 29 and 33 apart with thepin 34 engaging the end of the slot 31. The member 33- is provided witha short shaft or stud 40 rotatably mounted in the end thereof which alsoeX- tends through the end of a lever 41 and the end of an arm A42, theshaft or stud 40 Ibeing held inplace by a cotter pin 43. .The lever 4lis connected by means of a round rod 44,

' shown in dotted lines, to a similari leven 41 at the opposite end ofthe ironing machine frame and the levers 41 are pivoted on a stationarypivot 45 mounted on the frame 1. The arm 42 at 'the lower. end ispivotally lconnected at 46 to the end of a spring arm 47 whichis-attached to a cam 48 shown more particularly in Fig. 3. The cam 48 ispivotallymou'nted on agbolt 49 which is secured in the frame 1 and themember 12 is provided with a recess 50 for the said cam. The member l2is also provided with a slot 51 as shown in Fig. 3 through which thebolt49 extends and this bolt acts as a guide for the swinging of the member12 on the pivot 14.-

When the rod44 and levers 41 are raised from the position shown in Fig.1 to that shown in Fig. 3 the members 33 and'29 are forced to the rightthus moving the bearings 20 and .shaft 19 on'the arms-60 to the right ofthe slot 21 and moving the roller 22 to engagement with the face 24 ofthe ironing shoe'. Should a thick piece of clothing be positionedbetween the roller 22 and the shoe when the lever 41 is raised. therollerv will toward theironing shoe the driving mechanism drives theroller so that the clothes thereon cannot remain' in stationary contactwith the heated iron. The arm V47 is made of spring metal so that shouldthe teeth of the worm engage the outery faces of the teeth of the Wormgear the lever 42 may continue downwardly Without breaking any of theparts and, as the worm gear is rotated it will immediately move into thespaces between the teeth of the worm gear thus allowing the member 12to` move upwardly to the normal driving position shown in Fig. 2. Tostop the driving mechanism it is only necessary to move the rod 44 andlevers 41 to the position shown in Fig. 1 which draws the roller 22mounted on the arms 60 away from the ironworm 13 out of drivingengagement withY the worm gear 15. A casing is provided fol;` themechanism on the outside of the frame ends 1, though not here shown, andacts'as a guard to prevent the clothing from comingan contact with thegears.

' rom the foregoing description it becomes evident that the device isvery simple and efcient in operation, will not easily get out of order,is composed of comparatively few parts and is of consequent lowmanufacturing cost` and provides a device which accomplishes the objectsdescribed.

Having thus fully described my invention, its utility and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States ise `1.- In an ironing machine, a frame, an ironing shoeextending between' the ends of the frame, means for heating the ironingl yconnecting the end of each lever with the shaft of the feed roll, adriving mechanism for rotating the feed roll comprising a worm lll) .andgear, means for rotating the worm, a
